@RahulPatil Not according to the documentation. My man page (ifcfg) says: "For bonding slaves and bridge ports to skip the interface configuration." Hard to believe that this should have changed.

Actually none is one of the possible values for BOOTPROTO, not static according to the Red Hat Enterprise Linux Deployment Guide (for RHEL5). Another way to check this would be to run less /usr/share/doc/initscripts-*/sysconfig.txt followed by a search for BOOTPROTO.
